虽然超过39种灵长类动物被描述为花蜜饲养者，但没有研究记录这种行为可能对它们所消费的植物的繁殖成功产生负面影响。在这里，我们报告，第一次，大量的花破坏的热带树木Symphonia globulifera的食果蜘蛛猴，Ateles geoffroyi，并记录这种行为对坐果的不利影响。采集A. 1999年6月至2000年5月，在哥斯达黎加西南部奥萨半岛蓬塔里奥克拉罗的维达雷富吉奥（Refugio de雷富焦Silvestre）（8°39′N，83°44′E）的热带潮湿森林中，在460个接触小时内，详细的物候资料收集了10个S。这些树是猴子吃的，还有十棵在它们的家园范围之外，但在雷富焦的树。1999年7月至9月，S。球状幼体是最重要的摄食物种，占每月总摄食时间的86%至100%。猴子在S.结果发现，在80%的觅食回合中，花完全从树枝上脱落，在20%的觅食回合中，花没有花瓣，生殖部分受损。1999年11月和12月，猴子觅食的10棵树中没有一棵结果实，但在它们家外的10棵树中有7棵结果实。这些结果表明，一些灵长类动物可能在热带森林中的食花动物和随后的生殖成功率降低中发挥重要作用。未来的研究应侧重于评估这种觅食行为可能对该物种种群结构的长期影响，并评估灵长类食花动物对其他植物物种繁殖成功的影响。
Although more than 39 primate species have been described as nectar feeders, no studies have documented the negative affect this behavior may have on the reproductive success of the plants they consume. Here we report, for the first time, massive flower destruction of the tropical tree Symphonia globulifera by the frugivorous spider monkey, Ateles geoffroyi, and document the detrimental effect this behavior has on fruit set. Foraging behavior was collected from one troop of A. geoffroyi during 460 contact hours from June 1999 to May 2000 in the tropical humid forest at the Refugio de Vida Silvestre Punta Rio Claro (8°39′N, 83°44′E) in the Osa Peninsula in Southwestern Costa Rica. Detailed phenological data were collected from ten S. globulifera trees that the monkeys fed upon and ten trees that were outside of their home range, but in the Refugio. From July to September 1999 S. globulifera was the most important species consumed, representing from 86 to 100 percent of the total feeding time each month. Monkey foraging on S. globulifera flowers was destructive, detaching the flowers completely from the branches in 80 percent of the foraging bouts, and leaving flowers without petals and with damaged reproductive parts in 20 percent of the bouts. None of the ten trees where the monkeys were foraging set fruit, but seven of ten trees outside of their home range set fruit in November and December 1999. These results suggest that some primates may play an important role in floral herbivory in tropical forests and the subsequent reduction in reproductive success. Future studies should focus on evaluating the long‐term effect this foraging behavior may have on the population structure of this species and evaluate the effect of primate floral herbivory on the reproductive success of other plant species.
